Title: Low latency wireless messaging

Assignee: SPECTRANET TECHNOLOGIES LLC

Inventors: Jeffrey C. Adams

Abstract:
The patent describes technology for the wireless transmission of messages to remote receiving devices. This technology involves receiving a message, determining specific transmission parameters for it, and then transmitting the message according to these parameters. A key aspect is encoding the message to minimize message latency. The system is designed for message transmission via the ionosphere or other atmospheric layers, utilizing frequencies in the Medium Frequency (MF), High Frequency (HF), or Very High Frequency (VHF) spectrum. The disclosed technology is particularly aimed at achieving low-latency financial transaction execution, such as high-speed high-frequency trading.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method for Ionospheric RF Transmission):
  This claim describes a method for sending a message wirelessly at high frequencies through the ionosphere to a distant receiver. The process involves:

  1. Receiving an initial request to send a specific message.
  2. Compressing or shortening this message into an "encoded message" in a way that reduces the time it takes to transmit (message latency). The receiving device already knows what this shortened message means.
  3. Calculating specific transmission settings (like frequency, power, modulation) for sending this encoded message, taking into account both the desired low message latency and any mandated limits on the radio channel's bandwidth.
  4. Broadcasting the encoded message using these calculated settings over the high-frequency ionospheric band.

• Claim 8 (Device for Transmitting Messages):
  This claim covers a device (like a computer system) designed to send messages to a distant receiver. The device includes memory and processing power that enable it to:

  1. Encode a message into a smaller format to reduce transmission delay. This encoded message's meaning is already understood by the receiving device.
  2. Determine optimal transmission settings for sending the encoded message wirelessly. These settings are chosen to minimize message latency and adhere to predefined channel bandwidth restrictions.
  3. Control the actual transmission of the encoded message over a high-frequency ionospheric band using the determined settings.

• Claim 13 (Device with an Encoded Message Input):
  This claim describes a device that receives an already encoded message and then transmits it to a recipient. The device's memory and processing capabilities enable it to:

  1. Receive a pre-encoded message, which is a shortened version of an original message, specifically formatted to reduce transmission delay when sent via the ionosphere using high frequencies. The recipient device understands the meaning of this encoded message.
  2. Determine the appropriate transmission parameters for sending this encoded message, considering both the goal of low message latency and any set limits on the channel bandwidth.
  3. Transmit the encoded message over the high-frequency ionospheric band using these determined parameters.
